Many netizens are already well aware that the ONO Entertainment trainee is friends with the BTS member. Jang Moon Bok shared the details of their friendship and explained, "We became close in a bizarre way. We first met in the bathroom. We were in different classes but we met in the bathroom because it was located in the middle. V suddenly said to me, 'I enjoyed watching 'Superstar K'. I was surprised because he approached me first out of nowhere but then we became close."

Jang Moon Bok continued, "It was hard to see him after he made it at an audition and became a trainee. And then last year, we met and had a meal together. We jokingly took a lovely selca together but I didn't know that will become such a hot issue. He also cheered me on 'Produce 101' season 2. I get proud and also motivated when I see V receive love from all over the world. I also want to become a singer soon."
